Hypothesis Test For Positive Correlation. Assuming that the two variables are both normally distributed the test statistic is given by. Sample size n 0 10 782 0 10 396 0 15 346 0 15 176 0 20 193 0 20 99 0 25 123 0 25 64 0 30 84 0 30 44 0 35 61 0 35 33 0 40 46 0 40 25 0 45 36 0 45 20 0 50 29 0 50 16 0 55 23 0 55 14 0 60 19 0 60 11 0 65 16 0 65 10 0 70 13 0 70 9 0 75 11 0 75 8.
Multiple regression anova and t test correlation coefficient r reqd. T r n 2 1 r2 t r n 2 1 r 2. R r sample correlation.
We decide this based on the sample correlation coefficient r r and the sample size n n.
We decide this based on the sample correlation coefficient r and the sample size n. The p value for the two sided test is. Sample size n 0 10 782 0 10 396 0 15 346 0 15 176 0 20 193 0 20 99 0 25 123 0 25 64 0 30 84 0 30 44 0 35 61 0 35 33 0 40 46 0 40 25 0 45 36 0 45 20 0 50 29 0 50 16 0 55 23 0 55 14 0 60 19 0 60 11 0 65 16 0 65 10 0 70 13 0 70 9 0 75 11 0 75 8. Steps in hypothesis testing for correlation step 1.
